Pokemon Go received its first update earlier today, fixing several bugs players had experienced since the app's release. Some users on Reddit (via The Verge) are now claiming that the update (1.01) includes a game-breaking bug that locks them out of the app.
Users who sign into the app via a Pokemon Trainer Club account rather than a Google account are now unable to access the game and its servers. Dogecoin founder Jackson Palmer debugged the network traffic and found that the app no longer sends an HTTP request when you log in with a Pokemon Trainer Club account. This indicates that the problem is with the app itself, rather than being a server issue.
Currently, the only way for users with Pokemon Trainer Club accounts to bypass the bug is to avoid updating the app to version 1.01. Due to Apple's App Store regulatory policies, it's unclear how long it will take for developer Niantic to deliver a fix.
Since its launch last week, Pokemon Go has quickly become a worldwide phenomenon, sending Nintendo's stock soaring and earning an estimated $1.6 million in daily revenue with approximately 7.5 million downloads in the United States alone.
